A glowing exhaust means either clogged cat or it was running really rich. I'd go with the really rich situation considering you melted the plug boots. It sounds like your water pump has failed, causing a subsequent overheat that went unnoticed, could have been a bad gauge or sending unit, or just one of those flukes. When you put the cold water in, it caused the head to crack, then running the car will cause oil and gas to mix. Probably the easiest fix is to change the motor as you probably have bearing damage or cylinder damage. Hope this helps.

yeah what he said, either a plugged cat or stuck injector caused it to run bad, then the water pump goes, cold water breaks hot head.
he's right, save money, buy a yard motor to put into it (make sure you put a new water pump & Dealer thermostat too.
I bought a car missing a head, bought the head, put it all back together, spent a month finding the bad power wire to the computer, drove it for exactly 70 miles before it started knocking. New crank, rod, bored block, pistons, valve guides in head, timing chain set, crank position sensor, water pump, thermostat, complete gasket set & its back on the road. All work except machine work done by me, still have over $1000 into it, (its a DOHC)
Oh yeah, good luck finding a SOHC head if you decide to repair it, from what I hear finding a good one is like finding a diamond.
